Subject: [RFC 0/7] libperf: Add leader/group info to perf_evsel

hi,
moving leader/group info to libperf's perf_evsel.

This was asked for by Shunsuke [1] and is on my list
as a prereq for event parsing move to libperf.

I still need to do more tests, but I'd like to check
with you guys if there's any feedback on this first.

Also available in:
  git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
  libperf/groups

thanks,
jirka
